I have recently been learning about LZW data-compression ("A Technique
for High-Performance data compression", IEEE Computer, June 1984).
It is a dynamic compression algorithm that encodes byte strings as
12-bit codes (normally) on-the-fly.
Is MNP essentially the same thing, perhaps slightly modified? Or is
it something completely different. Most Macintosh Software is
compressed in LZW form by a tool called stuffit. The unix -compress-
command is based upon LZW compression. Has anyone ever tried sending
a StuffIt or -compress- file via MNP? Does MNP achieve any speedup at
all?

P.S. For you prometheus owners/modem buyers: I have a Prometheus 2400
modem ($299 on sale) that works fine, but I could probably have gotten
the same thing for <$200 in a Practical Peripherals modem. My
prometheus is a little flakey on local calls (2400 baud) about 10% of
the time. I thought maybe their microprocessor-based signal
processing might make a difference, but it probably doesn't.
